I'm a beginner for px4.I have installed px4 with Qgroundcontrol for my pixhawk but I can't find all of parameter about PID tuning such as MC_ROLLRATE_P MC_ROLL_P etc. How can I fix it?
You have not setup up your vehicle yet as shown by the red indicators on the setup pages. Finish vehicle setup first (at least airframe).
Thank you for your prompt reply.It's my fault,because after I installed px4 firmware and I found my firmware still is old firmware (ardupilot) which I don't know why? but I install px4 firmware again ,it's work for me.
